SYLVA NIA PENNSYLVANIA, ASSIGNOR TO P. H. MUR- ENNSYLVANIA, ACORPORATION 0F PENN- REFRIGERATOR CAR Application tiled January 22,1931. Serial No. 510,388;

This invention relates to refrigerator cars, and particularly torefrigerator cars having metal roofs. It has for its principal objectsto provide an eficient and compact arrange- 6 ment of the roofinsulation, which for a given headroom will decrease the over-all heightof the car or for a given over-all height will increase the headroomthereof; to provide for holding the insulation in place,

l0 to provide a simple arrangement for supporting the members that framethe hatch openings in the metal roof and for supporting said roofadjacent to said openings; and to provide for ease of assembly,cheapness of construction and economy of design. The invention consistsprincipally in the combinations and arrangements of parts hereinafterdescribed and claimed. y

In the accompanying drawings, which form part of this specification andwherein like symbolsrefer to like parts wherever they Fig. 1 is a planview of a portion of refrigerator car embodying my invention,

Fig. 2 is an enlarged vertical transverse section through onehalf of theupper portion of the car on the line 2 2 of Fig. 1.

Fig. 3 is a vertical transverse section through the eaves portion of thecar on 'the line 3-3 in Fig. 1, i

Fig. 4 is a vertical longitudinal section at the ridge of the car on theline 4 4 in Fig. 17 A Fig. 5 is a. vertical transverse section throughthe car at one of the hatch openings,

the section being taken on the line 5 5 of Fig. 1; and l,

Fig. 6 is a `vertical longitudinal section through the car at said hatchopening on the line 6 6 in Fig. 1.

Referring to the accompanying drawings, my invention is shown inconnection with a refrigerator car having a body frame comprising woodenside plates 1 that are connecto ed by metal carlines 2 preferably in theform of Z-bars arranged with their Webs vertical.

The wooden side plates 1 are preferably reinforced along their innerlower corners by means of metal members in the form of Z- bars 3 thatare arranged with their webs vertical and bearing against the innerfaces of said side plates and with their lower flanges extendingoutwardly beneath the side plates and with their upper flanges extendinginwardly. The Z-bar reinforcing members 3 55 are rigidly secured to theside plates 1 preferably by means of bolts 3a.

The refrigerator car is provided with a single course metal roofconstruction which f' preferably comprises metal load sustaining l(zolsheets 4 that slope downwardly from ridge to l eaves of the car and haveupstanding anges 5 along their adjacent side margins that are enclosedin inverted U-shaped seam caps 6 that have outstanding'l base flanges 7that overlie the adjacent side marginal4 portions of the roof sheets.The seam caps 6 are rigidly secured to the upstanding seam flanges 5 ofadjacent roof sheets by rivets 8 that extend horizontally through saidseam caps and said seam fianges. Each eaves end of the roof sheets andseam caps is bent downwardly and the adjacent end portions of the sheetsare rigidly secured by rivets 9 to the sloping top'flange of an eavesangle strip 10 whose vertical flange is secured to the outer face of theside plate by means of horizontal bolts 11. The lower portion of theeaves angle l0 is ofset outwardly so as to cap the upper ends of theside sheathing 12 of the car, thereby pre- 80 venting water and snowfrom reaching the interior of the car between the side plates and theside sheathing. Side fascia boards 13 are secured to the side platesbetween thel outer surfaces of the side sheathing 12 and the dependingeaves flanges of the roof sheets. The side fascia boards extend abovethe lower edges of the eaves flanges of the roof sheetsV and below thelower edges of the metal -sheet supporting angles 10 and thus serve toprotect said' angles land the securingg bolts 11 therefor from 4theweather. f The Z-shaped carlines 2 of the ear body are preferablylocated below the tops of the side plates to which they are rigidlysecured preferably by means of end fittings or brackets 14 that areriveted to the webs of said carlines and'have a laterally extending endflange that fits flatwise against the web of 1 the adjacent Z-bar sideplate reinforcing 10 member 3. Preferably the body or sub-car.

lines 2 are offset with relation to the vertical planes of the roofseams, which function after the manner vof exterior or outside carlines.The-base flanges 2a of the Z-shaped subcarlines 2 Iextend horizontallyfrom side plate to side plate; but the webs of said carlines graduallydecrease in depth from the middle .towards the ends thereof with theresult that the top flanges 2b of said carlines slope downwardly o nopposite sides of the ridge line of the car.l Each carline is reinforcedand stifened by means of wooden filler members and 16 that are securedto vthe op osite sides of the web of the carline by Abolts 1 and extendlongitudinally of the car-.

line substantially from end to end thereof. 'The'iiller member 15 hasits vupper surface inclined to-it the underside of thesloping top flange2b of the carline and has a horizontalpreferably of tongue-and-grooveboards is nailed or otherwiseirigidly secured. The carline filler 164rests upon the horizontal base flange 2a of the carline with its upperedge spacedthereabove and sloping downwardly from the middle of thecarline to the ends thereof in conformity with the pitch or slope of,the metal roof located thereabove.

Supported on top of the carline llers'l is a layer of relatively rigidinsulating material 19, such for instance as the material known in thetrade as Celotex, which extends in a continuous layer across saidcarline fillers from side late to side plate. The `space between this reatively rigid lower layer of insulating material 19 andthe metal l rooffilled with layers of relatively flexible .1 I insulating material 20,such for instance as 4. material of the kind known in the trade as DryZero. This relatively flexible insulating material extends continuouslyfrom -side plate to side plate and across the tops Y 'of the carlinesand is held in place at the i sides of thel car by means of woodencleats 21 that are presseddown upon the edges of such material4 and arenailed in this position to the inner side faces of said plates. Theportion of the relatively flexible insulating material 20 locatedintermediate the cleats 21 is held in place by means of the metal roofwhich serves to compress the material slightly between theunderside ofsaid roof and the relatively rigid lower layer of insulation 19.

Located beneath the metal roof-intermediate the two seams at each end ofthe car are two wooden carlines 22 that extend from side late to saidplate and are spaced apart longltudinally of the car. The woodencarlines 22 have their lower edges disposed horizontally at thelevel ofthe lower edges of the combined reinforcingl and nailing strips 15 ofthe Z-shaped carl1nes2 and thus serve as nailing strips for the ceiling18; and the 35 upper edges of these wooden carlines slope downwardly onoppositesides of theridge and serve as supportsfor the roof sheetylocated thereabove. The innermost carline of these two wooden carlineshas a nailing strip 23 secured to the side thereof that faces the middleof the car, which strip serves to support the adjacent end of therelatively rigid lower layer of insulation 19; and the adjacent end ofthe flexible insulation 20 is held in position' by wooden cleats 211that are' pressed down upon the edges'ofsuch material of `said* woodencarline. The insulationin v'and are`nailed in this position to'said sidef the space between the endmost wooden carline 22 and theend plate 25 ofthe car preferably extends horizontally from side plate to Iside plateand is preferably'held down upon the ceiling 18-bymeans of woodencleats' 26 that are nailedto the opposingfaces of said carline and said.end plate.

The two wooden carlines are 'connected on each side of the ridge by twowooden crossmembers 27 that cooperatewith said carlines to form a frameadapted to receive and su port a hatch frame 28, which isnailed to saidcarlines and said cross-members and extends upwardly` through an openingprovided therefor in the metal roof, the edges of such opening.being-flanged up around said hatch frame. By this arrangement, the twoend carlines 22, together with the cross-members 27, serve not only tosupport the hatch frame 28, but they also serve to support the metalroof where it iscut out to accommodate said hatch frame. I

By the arrangement described, the insulation is disposed entirely abovethe sub-carlines and is held in place between thevside plates by themetal roof.- It is noted that said insulation slopes downwardly from theridge to the eaves in a plane parallel to the slope of the roof and thesloping top surfaces of the insulating supporting strips of thecarlines, therebyovercoming the tendency for the insulation to shiftcrosswise of the car. It is also noted by thus arranging the insulationabove the carlines the outside height of the car may be reduced withoutdecreasing the -headroom thereof or the headroom of the car may beincreased without increasing the outside height thereof. It is fur.-ther noted that the portions of the body-frame below the main insulationare protected by the wooden ceiling boards so thatthere is v by andbetween said layer of relatively rigid What I claim is:
